A device for the radio stimulation of an antenna includes at least one transmission sub-assembly formed by an array of radiating elements and an array of photoelectric receivers; as well as a generator that synthesizes a set of electrical signals that are intended to excite each radiating element. The electrical signals are transmitted to the transmission sub-assembly in the form of modulated light waves that are multiplexed to form a composite laser beam that illuminates the array of photoelectric receivers. Each of the photoelectric receivers receives a light wave. The array of photoelectric sensors and the array of radiating elements have substantially identical arrangements. Each photoelectric receiver is connected to a radiating element in its array at a position identical to the one that said receiver occupies within its own or a position symmetrical thereto.

Device for radioelectric stimulation by self-referenced radiant panel

A stimulation device notably for testing radio reception devices is provided. It includes a signal generator delivering an amplitude-phase law for beam-forming purposes, transmitted in the form of a composite laser beam which illuminates a matrix of photodiodes of an emission subassembly with active modules separate from the generator, each wavelength of the beam carrying one of the signals defining the amplitude-phase law, intended for an active module. The device comprises means for measuring the orientation of the composite laser beam relative to the matrix of photodiodes of the emission subassembly and the distance traveled by the beam thereto, and correcting the phase law generated by the signal generator so as to neutralize the stray phase-shifts induced by these parameters on the signals transmitted to the emission subassembly.

Radiant-panel radio stimulation device

Disclosed is a calibration device of an imaging system for a moving carrier, the imaging system including: a support panel; an antenna array comprising radiating elements positioned on the support panel; and optical sensors capable of providing images and positioned on the support panel. The calibration device includes at least one optical pattern generator, each generator being secured to the support panel.

Device for calibrating an imaging system and associated calibrating method

The device includes at least: a set of optical and/or electromagnetic elementary sensors which are able to fly and means of command for piloting the flight of the sensors; processing means; a communication link between each sensor and the processing means; to produce an image of a given scene, the sensors fly while forming an array whose configuration is controlled by the command means, the processing means fusing the signals provided by the sensors with a view to delivering an image of the scene, the signals provided being representative of the scene.
